BY @Maaia-L WW EM United States Patent 3,107,123 A'iITrhCNT FOR WINDERS Cleve F. Christie, Knoxville, Tenn, assignor of twentyfive percent to Dovie A. Harrison, Knoxville, Tenn. Filed Aug. 21, 1959, Ser. No. 835,344 1 Claim. (Cl. 309-16) This invention comprises a novel and useful attachment for winders and more particularly relates to an attachment for converting a conventional broom winder into a machine for securing a mop head to a handle.

The primary purpose of this invention is to provide an apparatus which will facilitate the cutting of the yarn to toe proper length to form the strands of a mop head and the subsequent attaching or" the mop head to a handle of a mop. A further object of the invention is to provide a device 1n accordance with the foregoing object which shall be capable of attachment to a conventional machine for winding a mop head to a mop handle in order to convert the machine for use in forming mops.

Yet another object of the invention is to provide a device incorporating therein means for supporting a plurality of spools of rovinr or yarn to form the strands of a mop head; means for guiding and positioning the strands in a side-'by-slde relation and for cutting them; means for measuring the length of strands to be cut in accordance with the size of the mop to be formed; together with means for controliably rotating the mop handle and for tensrc-ning a tie Wire by which the 11100 head is secured to the handle.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE l is a side elevational view showing a mop Winding machine in accordance with this invention and which consists of a broom winder with attachments combined therewith for converting the same for winding mops;

FIGURE 2 is a top plan view of the arrangement of FiGUR l;

FZGURE 3 is a perspective view, parts being broken away, and showing in particular a portion or" the framework of the machine, of the adjustable motor mount for driving the arbor for rotating the mop handle, and means for tensioning the tie wire by which the mop head is secured to the handle;

FIGURE 4 is a perspective View of the cutting board which guides and positions the yarn in side-by-side relation and secures the same for cutting or severing of the yarn; and

FEGURE 5 is a perspective view of a measuring board by which strands of the yarn or roving of adjustable length may be measured preparatory to the severing of the same.

Referring first to FIGURES 1 and 2 it is to be understood that the complete apparatus disclosed therein which is specifically adapted for the forming of mop heads and the securing of the same to mop handles represents a conversion of a conventional broom handle and broom head winding machine in order to adapt it to the specific purpose of winding and securing mop heads to a mop handle. The conventional broom winder is designated generally by the numeral 19 and includes a supporting framework r2 having a fiat top surface 14 and in which is journalled a rotating chuck or anbor 15 through which ice drive pulley 18 which is driven by an electric motor 2% having a drive pulley 21! and a driving belt 24.

in applying the principles of this invention to the conventional broom winder in a number of additional attachment structures are provided. Thus, there is provided a support rack or support means designated generally by the numeral 26 and by means of Which a plurality of spools 23 of roving or yarn 30 are rotatably supported, this roving or yarn constituting the material from which the strands of the mop head are to be formed. The support rack 26 is disposed adjacent the right hand end of the machine 19' as shown in FIGURES l and 2.

As shown in FIGURES 1 and 2 a flat elongated plate 49 constituting a cutting board and whose construction is shown best in FIGURE 4, is secured to and rests upon the top surface 14 of the machine it? in such a manner that the two ends of the board 41? will overhang the machine Ill. The board 4i serves the purposes of a support means for the strands of yarn, a guide means for pcsitioning the yarn in sideby-side arrangement, a holding means for the yarn and a means whereby the yarn may be severed to the proper length to form the strands of the mop head.

n end member 42 is secured at one end of the board, and is provided with a pair of upstanding pegs or posts as at -34 between which a plurality of strands of yarn 3d are to pass as shown in PEGURE 2.

These posts or pegs id constitute the first of a series of guide means for the yarn. At its other end, the board 4% is provided with three longitudinally spaced strips or blocks designated by the numerals 46, 43 and 59-, and which are so spaced as to provide slots or channels as at 52 and extending transversely across the block. The two strips and project laterally beyond one side of the board as will be best apparent from FIGURE 2, and are provided with upstanding lugs 56 between which is pivoted as by a pivot pin 58 a rod 6% having a handle as thereon.

The rod oil is adapted to be pivoted down into the slot or channel 52 and to be secured in its lower position in any desired manner, and constitutes a clamping means with the channel 52 constituting a clamping channel. The arrangement is such that when the strands of yarn are disposed lengthwise of the cutting board 4t), they will pass across the channel 52 and then be clamped in this clamping channel or slot by lowering the rod thereinto.

A second pair of upstanding posts or guide pins 64 is secured upon the top of the strip dd and a third corresponding pair 66 is secured upon the block 48. As will be understood, the guide pins 64 and 66 are in alignment with each other in order that the plurality of strands of yarn or roving may be maintained in side-by-side relation lengthwise of the cutting board it? and across the clamping channel 52 and the channel 54 which constitutes a cutting channel.

Referring now especially to FIGURES 1 and 2 it will be observed that there is provided a support standard 68 of any desired character and suitably mounted upon a support member carried by the machine 10, and to the end of which is pivoted as at 79 a supporting strap or link 72 by which is carried a motor 74 having -a cutting blade 7 6 thereon. The arrangement is such that by swinging the strap 72 about its pivot 76, the motor 7d and the cutting blade 76 will be caused to move transversely of the cutting board, with the blade 76 riding in the cutting slot 01' channel 54 to thus sever the yarn stretched across this channel and held in place by the action of the clamping rod as previously described.

As further shown in FIGURES 1 and 2, the measuring board 8%} is fixedly secured as by bolts 82 to a portion of the framework of the machine 1% and extends horizon- 3. tally out beyond the end of the same. The structure of this measuring board is shown in FIGURE as conslsting of an elongated flat board having a mounting bracket 84 at one end thereof provided with apertures 86 for the reception of the fastening bolts 82 previously mentioned.

The bracket is mounted so that its vertical face is provided with a plurality of transversely extending longitudinally and vertically spaced apertures 88, for receiving in a selected position a measuring pin 90. The arrangement is such that the pin 90 may be moved in longitudinal adjustment along the board and when so positioned will constitute a measuring means whereby the ends of the strands 30 may be adjustably positioned so that when the strands are severed by the knife 76 previously mentioned, a strand will be formed of a sufficient length to constitute the strand of a mop head.

A manual control means is provided for selectively applying the power of the motor 21) to the arbor 16 for rotating the latter and the mop handle 92 which is disposed in and secured to the arbor for rotation thereby. This control means as shown more clearly in FIGURE 3 consists of a swinging mounting for the motor 29. This mounting consists of a pair of parallel beams 94 which are pivoted at one end as to a shaft 96 journaled in a portion of the framework 12 of the machine and which extends horizontally, these beams 94 being disposed on opposite sides of one of the corner posts 98 of the framework 12. The motor is bolted to these beams as by bolts 10%) and thus upon vertical swinging movement of these beams will be raised or lowered thereby tightening or loosening the pulley belt 24 and thus selectively connecting and disconnecting the motor from the arbor 16. A pair of tension springs 1G2 are secured to a cross plate 104 rigidly secured to the outer ends of the beams and thus serve to yieldingly urge the beams in an upward direction at all times. An eyebolt 166 is secured to this cross plate between the beams and has attached thereto a cable 108 by means of which the beams and therefore the motor may be iowered against resistance of the springs 102 in order to establish a driving connection between the motor and the arbor 16. The cable 108 in turn is entrained over idler pulleys 110 and 112 suitably journaled upon a frame cross member 114 of the supporting framework 12. The other end of the cable is secured to a lever 116 having one end journalled as at 118 to the previously mentioned corner post 98 and being provided with a foot pedal 120 on the other end operating the lever 1 16. It will be observed that a second lever 122 has one end secured to a pivot pin 130 which is journaled in the supporting frame 12. The other end of lever 122 is provided with a foot pedal 132 whose purpose is to be hereinlarfter set forth and the pivot pin 130 has secured thereto one end of a linkage assembly generally referred to by the reference numeral 134, see FIGURE 1, which in turn has its other end operatively connected to a conventional form of quick releasing collet generally referred to by the reference numeral 136 which may be disengaged to release the handle 92 upon downward pressure on pedal 132. The arrangement is such that by depressing the lever 116 through its pedal 120, the cable will be tensioned moving the supporting beams 4 downwardly against resistance of the spring and thus establishing a driving connection between the motor and the arbor causing rotation of the latter. When the pedal 120 is released, however, the springs 192 will return the support beams to their upper position, releasing the tension on the belt 24 and thus disconnecting the motor from the arbor.

Shown at 140 in FIGURES 1 and 2 is a coil of tie wire suitably supported at one side of the machine and from which is supplied the wire 142 by means of which the mop head 144, see FIGURE 3, is to be secured to the mop handle 92. As will now be appreciated, the tie wire is wound about the handle and about the mop head for securing the latter to the handle by rotation of the handle 92 through the operation of the arbor 16. In order to eifect this operation, it is necessary that tension be ap lied to the tie wire during this rotation in order that the same may be caused to tightly surround the strands of the mop head. For this purpose, the tie wire 142 extends through a staple, eyebolt or other guide means 146 disposed upon the framework, and then is wound about a tensioning pulley or drum 148 fixedly secured to a shaft 15E; whose ends are likewise journalled in the framework. From the tension drum 148 the wire extends upwardly above the frame, being passed over a guide roller 152 and from thence it passes downward to the mop handle 92 carried by the arbor 16.

Referring now especially to FIGURE 3 in conjunction with FIGURES l and 2 it will be observed that the tension drum 148, fixedly secured to the shaft is controlled through the action of a friction drum 154 likewise fixedly secured to the shaft. A friction belt or brake 156 is passed over the friction or brake drum 154, being secured at one end as to a portion 158 of the support framework so as to provide a stationary anchor for this end of the belt or brake. The other end of the same is secured as by a pivot 16% to one end of a link 162, which is secured to weight at its other end. The weight 165 is slidably positioned on lever 164 and retainable in an adjusted position upon the tightening of setscrew 167. The weight 165 normally imparts sufficient pressure to the friction band 169 for maintaining the desired tension on the wire 14- 2. The lever 164 is journalled upon the previously mentioned shflt 96 and a foot pedal 166 at the other end of this lever provides means whereby the lever may be depressed and thus release the tension of the friction belt or brake 156 about the friction pulley 15 and thus release the friction drag to the shaft 150, whereby the tension on the wire 14 2 passing over the tension drum 143 may be controlled.

The operation of the apparatus is as follows:

The plurality of strands of roving or yarn are drawn from their spools across the cutting board 40 and between the guide pins thereon, with the ends of these strands being drawn the requisite length to the measuring pin 90 of the measuring board 80. Thereupon the clamping rod is lowered into the clamping channel or slot 52 securely retaining the strands in place. The cutter is then manipulated causing the blade 76 thereof to pass through the cutting slot 54 and sever the strands. The strands are now ready to be formed into a mop head and secured to the mop handle. A mop handle 92 is secured in the arbor 16 and one end of the tie wire 142 is secured to the mop handle as by a nail 157, see FIGURE 1. The strands of yarn are now placed at their mid-portion upon the mop handle and the lever 116 is depressed tightening the pulley belt 24 and placing the arbor in rotation while at the same time, the Weight 165 applies tension to the friction band 156 and thus to the tie wire. As the arbor rotates, with the mop strands held thereto, the tie wire is tightly wound about the mop strands and thus fixedly secures the same to the handle. When sufficient tie wire has been wound about the mop strands and the handle, rotation is stopped, a further nail is placed in the handle and the tie wire wound thereabout and the wire is then broken off. It will be observed that in this process, each piece of yarn severed is twice the length of the strand of the mop so that when secured at its midportion to the mop handle, there will result two strands of the proper length.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de scribed, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A mop making machine comprising a machine support, an arbor for receiving and rotating a mop handle rotatably mounted on the support, means for supplying mop yarn, means for supplying wire adjacent the arbor whereby the arbor may rotate the handle and mop yarn on the handle so as to wind the wire on the handle and yarn and secure the yarn to the handle, said means including a tension pulley enveloped by a loop of said Wire and rotatably mounted on said support, a brake member secured to said pulley, a brake shoe adjacent said member, manual operating means connected to said shoe so as to urge it away from said member, a weight connected to said shoe so as to urge it by a constant force into frictional contact with said member, said manual means connected to said shoe so as to vary the tension in said wire during operation of the machine.
